9c869edac591977314323a4eaad5f7633fca684f broke voyager again
rather subtly because it already had its own topology exporting
functions, so now each CPU gets registered twice.
I think we can actually use the generic ones, so I don't propose
reverting it. The attached should eliminate the voyager topology
functions in favour of the generic ones.
I also added a define to ensure voyager is never hotplug CPU (we don't
have the support in the SMP harness).
